Background

PX-866 is a potent derivative of wortmannin that irreversibly inhibits PI3 kinase (1). Research studies demonstrate that PX-866 elicits a more sustained inhibition of PI3K than wortmannin. While both chemicals inhibit Akt phosphorylation similarly at short time periods (1-2 hr), PX-866 also demonstrates inhibitory effects for extended time periods (24 hr) at lower doses than wortmannin. This difference may be attributed to wortmannin’s short half-life of 10 minutes and the reduced cytotoxicity of PX-866 (2). PX-866 inhibits the PI3K pathway through down regulation of cyclin D1 protein, which is responsible for regulating cell cycle progression and autophagy induction (3). Additional research shows that PX-866 inhibits cell migration in cancer cell lines (2).
